What are signs of a dysregulated nervous system?

Common signs include: persistent muscle tension, sleep disturbances, digestive issues, disproportionate reactions to minor stressors, difficulty calming down after stress, feeling on edge or hypervigilant, emotional numbness, rapid mood swings, chronic irritability, brain fog, racing thoughts, and difficulty being present. Physical symptoms like heart palpitations, chronic fatigue, and weakened immune function can also indicate dysregulation.
